HP on LS2 E-Force?
I purchased the 3.5 in Pulley however I don't think it is worth all the trouble of upgrading the fuel system for such a small gain since I will not be upping the HP to much over 500 rwhp.
Just trying to find out what HP I would be looking at with the standard 554 HP kit. The only other Mod I have on the 2006 A6 is LG headers. Thanks for any information.
PS, Edlebrock also said to use the standard spark plug with the 554 hp kit, just wondering if you guys are staying with that recommendation or whether you are going to a colder plug.
Just trying to get all the opinion here from guys that have already installed the kit.

Also, you have a 2006 6L80E (A6), which does not have the updated valve body, pump or seals. In late 2009/2010, GM made modifications to the 6L80E to resolve a few issues (even a TSB out - which you're probably past being serviced for).. What this means is, you are susceptible to the 2-3 shift flare, as well as low line pressures which causes the 4-5-6 clutch pack to burn up. Ask me how I know? 07 A6 here, currently being shipped to Circle D for a complete rebuild with their new extra wide clutch packs and 300M intermediate shaft (they also swap the valve body/pump/seals to the current parts from GM, and then do more modifications I haven't mentioned).
I would recommend you get the transmission tuned, as it won't last long being supercharged without the tune being modified. And then, there's no guarantee how long it will last anyway because of what I mentioned above. The clutches from the factory are too small/too few and a joke when you make extra power.
I know it's probably not what you want to hear, but adding power is only one piece of the puzzle. You've also gotta think about your drivetrain to make it handle that additional power. If you want, you can go ahead and give Circle D a call. They'll tell you everything you need to know. Until recently there was only one clutch pack upgrade available, which was said to be fine for 500-600rwhp. Circle D's new extra wide clutch pack (which is ONLY usable with their 300M intermediate shaft which allows these wider clutches) has twice the surface area of the OEM clutches. They have some customers running up to the 1000rwhp range, and they test all their new stuff on a 6L80E in their shop Camaro SS.
So anyway, what it all boils down to is.. horsepower at the engine is cheap. But you've gotta add up all the other stuff as well, to make your build be reliable and have a long life. Also, tuning is very important, so get a shop that has done a few of these LS engines to tune yours.
If you do everything right, but you drive it kinda hard, you can expect anywhere from 9k (that's how many miles my engine lasted before it exploded) to ~35k miles. Quite a few people have their engines let go in that range. If you never beat on it, it may last longer. If you upgrade the fuel system, it may last longer. If you spray meth, it may last longer. But our engines aren't built for boost, there's a reason the ZR1's LS9 has a low 9.2:1 compression ratio and forged internals. The LS2 and LS3 have hyper-eutectic pistons, and 10.9:1/10.7:1 compression ratios (respectively)
But, to answer your original question, see this:
As a point of reference, I have the 1593 kit on my otherwise bone stock 2007 6 speed. I also have the 3.5" pulley. I still run the stock fuel pump and NO BAP. The tuning showed the BAP was not necessary for my car.
You can see from my dyno chart that I'm getting anywhere from 3.5 to 8 PSI of boost.

Ken (Motorhead) makes a good point too - I still have the stock runflats on my car and drive the car back and forth to work for the most part. I'm thinking of going back to the 3.875 pulley in order to make 1st and 2nd gear a little more useful.

I'm really surprised that the E-force even broke 500RWHP. If/when I go FI I'll just use a ECS kit with meth and upgrade the drivetrain and still be close the the price of the eforce. Believe it or not 500 RWHP will become old really fast. You will be wanting more power sooner than you think(just one of the many reasons I would go with an ECS kit). Just my $.02. Enjoy the new power.
Here is some more information on my 2006 A6.
I had a Vortech (A&A type) supercharger which was putting down 521rwhp at 6 psi and that was plenty enough for me. I am not planning on anything more. I am only getting the E-Force since I was getting tired of my car and just figure that the PD supercharger would be different from my old supercharger. I don't drive my car hard and don't really go to the drag race much.
I think I will be happy with the current stock 3.875 in pulley however would just like an idea on what kind of rwhp number and boost pressure I would be seeing.
I did purchase the 3.5 in pulley however I don't think I will be putting it on unless my HP is really low (something like 450rwhp or less).
My A6 was tuned when I got my supercharger tuned so hopefully that will make my A6 last longer but I don't really do much hard driving.

I say bail out of the E-Farse install while you still can!

Not looking for more HP but just a different driving experience (I hope).
To about 4500rpm, the E-Force has more torque than the A&A kit. After that, the centrifugal maintains a pretty flat 500ft-lb from 4750ish to redline. Also, about 4750 the E-Force power gains really start to flatten, where the A&A continues to go up nearly 80rwhp more. You've got an A6, when you're WOT and it's shifting, you will not be down low in the band, see what I'm saying? The A&A kit is more street-able down low because you can hook better/less torque strain on your A6, and because when WOT you will be faster than the E-Force because you aren't flattening off, you're still making more power.
Burning more rubber will definitely be a different experience though

My situation and feelings exactly and the reason I'm doing an E-Force install the end of this month. I can't remember how many times I actually went over 4500 rpm and the E-Force is solid in the range I drive in. I have no intention of doing any racing of any kind. And yes
I've definitely had a lot of fun with the C5, but for my C6 I'm just looking to have a little fun on the street here and there.
There is something to be said for keeping the combo simple and just having fun. You can very easily lose sight of that and end up with a monster.
Since you also have headers I'm assuming you will go with a custom tune?

Contrary to the "centri owner's myth" there is plenty of room to grow with the Edelbrock kit if a guy wanted to go there. Redline Motorsports had 633/575 (at the rear wheels) on the Edelbrock nearly a year ago...right after the supercharger hit the market!
A casual search over on the Camaro forum turned up a "732.6RWHP 738.1 lbs TORQUE" forged motor running the same E-Force head unit as used in the base kit.
C6 Vette last April...
